Question: Consider a roller coaster as it travels near the bottom of its track as sketched in the figure below. At this point, the normal force on the roller coaster is four times its weight. If the speed of the roller coaster is 18 m/s, what is the radius of curvature of the track? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
